NB Рукђ "hand" vs. кќсть "hand." The word кќсть is somewhat technical (i.e., anatomical) in style and less common than the word рукђ. Кќсть suggests the bones rather than the flesh, and is used only with modifiers that describe visible properties. Thus, such adjectives as влђжная "damp," горїчая "hot," лћвкая "nimble," can only be used with рукђ, but not with кќсть. Certain verb phrases which may include рукђ are not allowed with кќсть: потирђть рџки "to rub one's hands," взїть в рџку "to take in one's hand," держђть в рукљ "to hold in one's hand," etc. Compare взїть зђ руку "to take someone by the hand," which is a very common expression, and взїть за кќсть, which is almost a technical description of the same movement, appropriate for a doctor looking for pulse, or a coach showing a specific movement, etc.
